Objective  To investigate the clinical effect of ultrasound-guided therapeutic percutaneous puncture catheter drainage (UG-TPPCD) in the treatment of severe pancreatitis patients complicated with peripancreatic abscess.

  Methods  A total of 126 severe pancreatitis patients complicated with peripancreatic abscess were selected and randomly divided into control group (n=63) and study group (n=63). Open surgery and drainage was used in the control group, while UG-TPPCD was used in the study group. Effects were compared between two groups.

  Results  The total effective rate of the study group was 93.65%, which was significantly higher than 71.43% of the control group (P < 0.05). The remission time and hospitalization time of symptoms and signs in the study group were significantly shorter than those in the control group, while the levels of serum amylase, urine amylase, white blood cell count (WBC) and C reaction protein (CRP) in the study group were significantly better than those in the control group (P < 0.05). The incidence rate of complications in the study group was 6.35%, which was significantly lower than 19.05% in the control group (P < 0.05).

  Conclusion  UG-TPPCD is effective in the treatment of severe pancreatitis patients complicating with peripancreatic abscess, which can improve the symptoms and signs of the patients, enhance the curative effect, relieve the inflammatory reaction and reduce the complications.
